BOLT-HEADING IMPLEMENT.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed May 3, 1904. Serial No. 206,231.

To all whmn it rncty concern:

Be it known that I, lVILLIAM H. SAYER, a

citizen of the United States, residing at Adams, in the county ofUmatilla and State of Oregon, have invented a new and usefulBolt-Heading Implement, of which the following is a specification. Thisinvention has relation to bolt-heading implements; and it consists inthe novel construction and arrangement of its parts, as hereinaftershown and described.

The object of the invention is to provide an implement adapted to beused in combination with a vise for holding the bolt while the head isbeing formed upon the same. It is understood that during said operationthe strain incident to the pounding is severe upon all implements usedin such operation, and consequently the implements in order to beserviceable, must be constructed in a substantial manner and to be asfree from weak points as possible. The forming of boltheads betweenclamping-jaws is unsatisfactory, for the reason that the blows exertedtransversely of the holding force applied to the vise-jaws drives thebolt or rivet from between the same, so that it is frequently necessaryto loosen the vise and readjust the bolt or rivet during the process ofheading. This entails vexatious delays and annoyance and preventssatisfactory results and uniformity of the head.

WVith the improved implement hereinafter described the bolt or rivet isnot only firmly supported and the tendency to longitudinal movementunder the heading force materially decreased, but the implement itselfmay be effectually supported and held from displacement transversely ofthe clamping means. At the same time the implement is so constructedthat the clamping means may be. applied on diametrically opposite sidesof the pivot that secures the members which constitute the implementtogether, and thus the hinged or pivotal point of the said mem bers isrelieved of the strain incidental to the force of the blows upon the endof the bolt. Furthermore, the implement may b e adjusted along itsentire length between the jaws of a vise, and such adjustment is veryconvenient in the formation of heads upon the same characters of bolts.

In the accompanying drawings, Figure 1 is a perspective view of theimproved implement. Fig. 2 is a transverse section, en-

larged, showing the device supported between vise-jaws.

The implement comprises the two members 10 and 11, hinged together atone end at 12 and with the other ends merging into the handles 13 and14. In the adjacent faces of the members 10and=gl liare formedsemicircular recesses 15 and 16, which when the members are unitedregisterwith 'each other and form circular apertures to receive andsupport the bolts or rivets to be operated on and will be graduated insize to adapt them to difi'erent sizes of such articles.

The portions 10 and 11 of the implement are of the same size throughouttheir length,

so that their outer faces are parallel, and extending laterally from theupper outer edges are flanges or ribs 17 and 18, said flanges extendingat thehinge end beyond the hingepintle. The flanges are desi ned to bearupon the clamping means, suc as the jaws of a vise. By reason of thefact that the said flanges extend beyond the hinge-pintle of the saidmembers the clamping-jaws of the vise may be brought togetherdiametrically opposite about said pintle, and thus the hingepoint orweak point of the implement is protected against the heavy strainincidental to the operation of forming the head upon a heavy bolt. Thisfeature is material in preserving the integrity of the implement.Furthermore, by reason of the fact that the outer portions of the sidesurfaces of members 10 and 11 are in planes without shoulders or lateralprojections the said implement may be shifted to any desired positionbetween the jaws of the vise, and thus, if it is intended to form thehead on a very long bolt, the rod may be placed in the recesses 15 and16 and may extend down to one side of the vise. By reason of the factthat the said lower outer surfaces of the said members 10 and 11 arewithout lateral projections or shoulders the implement may be adjustedbeyond either side of the vise.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

An implement of the class described comprising members hinged togetherat one end and provided with handles at the opposite ends, said membershaving body portions of uniform width throughout and being provided intheir inner edges with oppositelydisposed recesses, each said memberhaving ICC on its outer-sideaflange thei ip, :er'surface of of: thehinged members, said membershaving which is in thesame plane ast face ofthe member, said flanges extend ng along the entire lengthrof: themembers from points diametrically opposite the center of thehinge-pintle thereof to thefhanill'esthereof, those portions of thesides of the members vbeneathsaidflangestbeing in vertical planeswithout lateral projectionsor shoulders and the sides of the handleslying within the vertical planes of such under portionsof the sides 1e'upper -sur' their hinged ends provided with arcuate surfaces whichbear directly against each other.

In testimony that I claim the foregoing as r 5 my own I have heretoaffixed my signature the presence of two Witnesses.
